The good performance of a lead-acid battery (LAB) is defined by the good practice in the production. During this entire process, PbO and other additives will be mixed at set conditions in the massing procedure. Consequently, an active material mainly composed of unreacted PbO, lead sulfate crystals, and amorphous species will be obtained. Later, the

grid plates – the plates have a grid like honeycomb type on the positive plates and lead oxide with powdered sulfates on the negative plates. The active material is usually made into a paste by adding sulfuric acid and water. The paste acts like a sponge soaking up the electrolyte that is added later and keeping this electrolyte close to the plates to improve the
However, the sulfation of negative lead electrodes in lead-acid batteries limits its performance to less than 1000 cycles in heavy-duty applications. Incorporating activated carbons, carbon nanotubes, graphite, and other allotropes of carbon and compositing carbon with metal oxides into the negative active material significantly improves the overall health of lead-acid
